POLE-SUPPORT.

SPECIFICATION forming part of Letters Patent No. 684,451, dated October15,1901. Application filed dune 13, 1901. Serial No. 64,467. (No model.)

T0 to whom, it may 001 m.-

Be it known that LEDWARD' S. MOWRY, a citizen of the United States,residing at Middletown, in the county of Middlesex and State ofConnecticut, have invented certain new and useful Improvements inPole-Supports, of which the following is a specification, referencebeing had therein to the accompanying drawings.

My invention relates to improvements in pole-supports of that classwhich are designed to adjustably support a flag or other pole at variousangles of inclination. It is especially designed for supportingflag-poles upon the deck of a vessel; but, however, I do not limitmyself to this particular use.

The object of my invention is to construct a device to support a flag orother pole and arrange and secure the parts together so that the angleof inclination of the pole may be varied and held rigidly againstmovement in any of its adjusted positions, as well as to make the deviceof the fewest possible parts which can be produced at the minimum cost.

To these and other ends my invention consists in the pole-support havingcertain details of construction and combination of parts as willbehereinafter described, and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designatelike parts in the several views, Figure 1 is an elevation of the devicecomplete. Fig. 2 is a transverse section thereof; and Fig. 3 is asectional view of the base-plate, taken upon a plane at right angles tothe section of the base-plate shown in Fig. 2.

My device consists, essentially, of a base member and a socket member,within which the pole is held and both secured together by aball-and-socket joint and a threaded bolt.

Referring now to the drawings, the numeral 1 designates thebase-plate,which is provided.

I 7', which passes freely through the slot 3 and is threaded into thesocket member.

The bolt 7 is provided with a square head 8 and is held against rotationby the integral lugs 9 0 within the interior of the boss 2. It

ings that the flag pole or staff can be inserted within the bore of thesocket member 4 and that the position of the socket member in relationto the base member can be varied by reason of the ball-and-socketconnection, it being necessary only to rotate the socket member 4 aboutits axis, and thereby release or tighten its threaded engagement withthe bolt 7. When released, the socket member can be shifted to variousangles of inclination from the base member, one of which is shown bybroken lines in Fig. 1, the bolt 7 moving through the slot 3 in the boss2. After the desired position is obtained the socket member 4 is againrotated about its axis and the parts are securely fastened together.Ordinarily the rotation of the socket member 4 about its axis by thehand is sufficient to hold the parts together; but to secure the partsstill more rigidly I have provided a hexagonal portion 10 upon the lowerend of the socket member, which can be engaged bya wrench.

It is understood, of course, that the baseplate is attached to somerigid part, as the deck of a vessel, a wall, or other like part, by anyof the means commonvto the art.

The form or construction of the base-plate is not material to myinvention, as any form or style of base-plate can be used equally aswell as that herein shown.

There are minor changes and alterations that can be made within myinvention aside from those herein suggested, such as providing thesocket member with a semicircular boss and the base-plate with aconcaved recess, and I would therefore have it understood that I do notlimit myself to the exact construction herein shown and described, butclaim all that falls fairly within the spirit and scope of my invention.

What I claim as new, and desire to secure by Letters Patent, is-

1. In a pole-support, the combination with a base member; a socketmember, having means for attaching the pole thereto; and

is apparent from the description and drawmeans controlled by therotation of one of said members for separably securing said memberstogether, the said members having a ball-and-socket engagement with eachother.

2. In a pole-support, the combination with a base member; a socketmember; one of said members having a semicircular boss thereon and theother member being provided with a concaved recess forming a seat forsaid circular boss; and means, controlled by the ro tation of one ofsaid members, for separably securing said memberstogether.

3. In a pole-support, the combination with a base member; a socketmember; one of said members having a semicircular boss thereon and theother member being provided with a ooncaved recess; a threaded part forrigidly securing said members together passing loosely through one ofsaid members and threaded into the other of said members, and means forholding said threaded part against rotation.

4:- In a pole-support, the combination with a base member; a socketmember; one of said members having a semicircular boss thereon having aslot therethrough, and the other member being provided with a concavedrecess; a threaded part for rigidly securing said members togetherpassing loosely through the 7 slot in said boss and threaded into theother 7 V r j of said members, and means for holding said threaded partagainst rotation.

5. In a pole-support, the combination with the base member 1 having asemicircular boss 2 thereon provided with interior lugs 9 of the socketmember 4 having a concaved recess 6 therein forming a seat for saidsemicircular boss; and a bolt 7 passing loosely through said base memberand threaded into said socket member and held against rotation byengagement with said lugs, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
